Has anyone dealt with coronary artery calcium score changes on glp-1?

Positive "side effect" of cardiovascular risk: my blood pressure dropped so much that I'm now off metoprolol entirely!

SUSTAIN-6 was the first CVOT to show cardiovascular benefit with semaglutide, relevant to cardiovascular risk. In 3,297 T2DM patients with high CV risk: MACE HR 0.74 (95% CI 0.58-0.95, p=0.02)[1].

Notable: the retinopathy signal in SUSTAIN-6 (HR 1.76) was subsequently attributed to rapid A1C reduction in patients with pre-existing retinopathy — not a direct drug effect. This has been confirmed in longer-term follow-up studies.

One thing that is still open after newstart_MO’s answer:

How would you tell the difference between that and the alternative explanation?

NNT calculation for cardiovascular risk clinical endpoints: NNT = 1/ARR (absolute risk reduction).

From SELECT trial: MACE at 39 months — 6.5% semaglutide vs 8.0% placebo. ARR = 1.5%. NNT = 67 over 3.3 years.

Compare to established therapies:

These NNTs are clinically meaningful and comparable to accepted cardiovascular interventions.

Vitamin deficiency cascade with cardiovascular risk: after 6+ months of reduced food intake, I developed a subtle but important pattern: low B12 → elevated homocysteine → increased cardiovascular risk marker.

The connection: B12 is a cofactor for homocysteine metabolism. Without adequate B12, homocysteine accumulates. This is ironic — taking a CV-protective medication while developing a CV risk factor from reduced nutrition.

Solution: comprehensive vitamin supplementation and regular lab monitoring. Don't let the medication's benefits be undermined by nutritional deficiencies.

Bookmarking. The distinction being drawn above is the one nobody else makes. Printing the relevant bit and taking it with me.
